PRINTING ATTACHMENT FOR ENVELOPE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 432,785, dated July 22, 1890.

Application filed August 22, 1887. Serial No. 247,538- (No model.)

To aZZ whom, it may concern; 1

Be it known that I,LoUIs PETER BOUVIER, machinist, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, 5 have invented an Improved Printing Attachment for Envelope-Machines, of which the following is a specification.

The object of the invention is to design a printing attachment for envelope-machines [O which will print or emboss the envelopes during the period that they are being man ufactured, the entire process being accomplished substantially as fast as though the envelopes were being made plain; and the invention [5 consists, generally, in the construction or arrangement of parts hereinafter disclosed in he description and claims,-wl1erebya simple printing attachment is placed between the picker and folder of the envelope-machine, and so operated from the main shaft of the machine that it prints the blank while it is passing from the picker to the folder, the picker, printer, and folder being so timed relatively with each other and with the motion of the carrier that the picker, printer, and

folder shall substantially operate simultaneously, the picker acting on the top blank of the pile, while the printer is acting on the blank just removed from the picker by the carrier, and the folder is at the same time acting on the blank last delivered from the printer, the whole being arranged and operated substantially as and for the purposes hereinafter more particularly explained. 5 Figure 1 is a perspective view of a portion of the table of the machine, exhibiting a View of the printer and showing'the mechanism for operating the inking-roller thereof. Fig. 2 is a detail view of the platen. Fig. 3 is a 40 detail view of the connecting-rod for conveying mot-ion from the main shaft to the rock shaft operating the inking-roller. Fig. i is a detail View of the cam and connections for operating the rock-shaft of the inking-roller.

5 Fig. 5 is a perspective view of a portion of the machine from the side opposite that exhibited in Fig. 1. Fig. 6 is an enlarged detail view of the type-bed for'oarrying the type-frame or embossing-plate and also the operating devices therefor.

Figs. 7, s, o, 10,

11, and 12 are detail views'of the printing attachment. Fig. 13 is a skeleton view, in longitudinal section, showing the relative positions of the printer and folder with an additional section through the picker, which is a wellknown device. Fig. It represents a perspective view of the portion of the machine which is represented in Fig. 5, with the addition of the in k-foun ts,the ink-transferring rollers therein, the inking-roller, means for reciprocatingthelatter,and the means fordriving said ink transferring rollers from the main shaft. Fig. 15 is a'vertical section of the machine, showing the picker, printer, and folder in their relative positions and the mechanism for operating the same.

. In the drawings the same letters of reference indicate the same or corresponding parts in each figure.

Although my printing attachment is applicable to other eni 'elope-machines, it is specially constructed to be applied to an envelopemachine patented by me in the United States on the 30th day of June, 1885, under No. 321,183. In this machine carriers are employed for the purpose of conveyingthe blank from the picker to the folder, the said carriers having imparted to them a reciprocating motion, so that after having carried the blank from the picker to the folder it returns to the picker in time to receive the next blank elevated by the latter.

In adapting the machine for my presentinveution I separate the picker and foldersufficiently far apart to permit the printer to be placed between them. The relative positions of the three are shown in Fig. 13, in which A represents the picker, B the printer, and C the folder.

The letters a and Z1 represent the fingers on 0 the carrier, by which fingers the blanks are held on the carrier while thelatter is moving that is to say, the fingers a move the blank from the picker A to the printer B. The stopfingers D, being operated as hereinafter described, arrest the motion of the blank, so as to hold it in exact position to receive the impression from the printer, and are immediately moved out of the way of the blank when the printing has been effected, so as to per- I00 mit the fingers Z) to convey the blank just printed to the folder 0, after which the carrier returns for the next pair of blanks-that is to say, as before stated, the fingers a remove the blank just lifted by the pick er to the printer, and the fingers I) remove the blank just printed to the folderso'that it will be seen that the gumming by the picker,the printing or embossing by the printer, and the creasing by the folder are accomplished substantially as fast as the gumming and creasing in a simple envelope-machine.

Having explained the general object and operation sought to-be attained by my invention, I shall first proceed .to describe in detail the mechanism involved in its construction. \Vith that'view I shall first draw attention to Fig. 5, in which the mechanism for gaging and holding the blank on the carrier is exhibited.

E is the main shaft of the machine. 7

F is the rod for conveying motion from the main shaftE through cam E and pivoted arm E to the rock-shaft G, which rock-shaft operates the picker in the same man ner as in the machine referred to in the commencement of this specification, or by means of the arm G, attached to said rock-shaft and pivotallyconnected to said picker, as shown in Fig. 15. The stop-fingers D are connected, as indicated, to the rock-shaft II, which is itself con nected to the rock-shaft G by the red I, the said rod I being rigidly connected at its lower end to the rock-shaft H, its upper end being provided with an anti-friction roller 77., which is held against the cam J, fixed to the rockshaft G, and arranged to actuate the rockshaft I-I, so as to cause the fingers D to fall upon the conveyer or carrier in time to arrest the motion of the blank in the exact position that it should remain during the period that it is being printed. A spring K, connected at one end to the rod I and at its other end to the frame L, as shown in Figs. 5 and 14, serves to hold the anti-friction roller on the rod I against the cam J, as specified.

In order to prevent the blank being dragged down by the type as they retire after imparting their impression onto the blank being printed, as hereinafter explained, I provide two stop-fingers M, so operated that they are brought down and caused to press upon .the top of the blank against the guides supportarm 70, as indicated.

ing it, and there hold it while the type is being moved from the blank. These fingers M derive motion from the rod 1, which is connected to the rock-shaft N, which is itself connected by the crank O and rod P to the This arm is pivoted on the shaft 71', and is held by the spring Z against an eccentric m, fastened to the main shaft E, said eccentric being set thereon and of such a throw that the requisite movement to the stop-fingers M is produced, as described,

by the revolving of the main shaft E.

Q is thetype-bed, on which the type-frame or embossing-plate is supported, as shown in Figs. 1, 5, 6, 13, and 14. This type-bed has a rack (Z, attached to and extending from its bottom side, which rack fits into a bracket R, attached to or forming part of the frame of the machine. In this bracket, as shown in Fig. 6, a gear-pinion S is carried, so as to mesh with the rack d. The pinion S is fastened to the shaft T, which is journaled in the bracket Q to bring the type-frame or embossing-plate 7 carried by it against the bottom surface of the blank,-which is at that moment held over it by the means hereinbefore described, a platen-plate U being placed, as indicated, to receive the upward pressure. This platenplate is shown in dotted lines in Fig. 1 and in detail in Fig. 2. It will be seen that it is supported on the head V, formed on the frame L, and that it isadjustable vertically by the screw XV, pinching-screws j being provided for the purpose of adjusting any slight variation in the horizontal position of the said platen U.

Before describing in detail the ink-distrib-' uting apparatus of my printer I shall first draw attention to the mechanism for driving the inking-roller.

On reference to Figs. 1 and 14 it will be noticed that the inkroller nis connected by the rods 0 and arms 0 to the crank-shaft p, which is j ournaled in brackets attached to the table of the machine. An arm X is fixed at one end to the crank-shaft p, and has a socket formed at its other end to receive the ball q, formed on the end of the rod Y. A similar ball q is formed on the other end of the rod Y and fits into a socket formed in the end of the arm Z, which is suitably pivoted in the frame of the machine, as indicated, and provided with an anti-friction roller 2 to IIO rest upon the cam 0', which is attached to the face of the gear-wheel s,- driven from the main shaft E, a-s'shown in Figs. 1 and 4. This cam has the proper throw to cause the inking-roller n to pass over the face of the type,

and the speed of the said cam is so timed that each time the type falls from the blank, which is removed, as before described, the inkingroller it passes once more over' the surface, the said inking-roller receiving a fresh supply of ink first on one side and then on the other side of the type, suitable ink-fountsbeing located, as shown, for that purpose. Theball-and-socket joint mentioned, formed at either end of the rod Y, is a necessary expedient, owing to. the fact that the arm X and the arm Z must have a certain amount of play,

being arranged at right angles to each other.

In order to adjust the distance of the stroke or movement of the in king-roller,I divide the rod Y, as at Y, Fig. 3, connecting the" two divisions by a screw and nut, so that the saidrod may be lengthened or shortened toa certain extent, as may be required, to alter the distance of the stroke of the inking-roller, and bring it into more or less intimate contact with the rollersin the founts. .This ink-- ing-roller is shown in detail in Fig. 11. In this figureit will be seen that at each end of the inking-roller n a narrow roller 25 is placed, being rigidly fitted to the spindle of said inkingroller between its ends and the bearing-boxes it, each of which is shaped substantially as shown in Fig. 12, and each is fitted into ajaw formed in the guide-blocks l) which are fitted to and move with their respective guiderods 10.

at represents springs, one of which is attached to each guide-block o, and acts upon the bearingbox a in each, so as to.11old the said boxes in position.

Q/ are tracks provided for the rollers t. These said ink-fount frames, so that the said tracks may be moved vertically for the purpose of raising or lowering the inking-roller n, wh ch is supported by said rollers t, resting on said tracks 3 By thus providing means for the vertical adjustment of said tracks I am enabled to make the inking-roller n wipe over the surface of the type j nst sufliciently to spread enough ink over their surfaces for the purpose of properly printing, which is evenly accomplished, as said inking-roller is caused to revolve by the action of the rollers t on the tracks 1 One of the ink-transferring rollers B, from which the inking-roller n derives its supply, receives motion from any convenient moving part of the envelope-'machine-as, for instance, from the sheave-pulley e on the main shaft E, under which the rope or cable c passes, thence over the guide-pulleys b on the ends of the transferring-rollers, and thence back to said sheave-pulley e on the main shaft, as shown in full lines in Fig. 14 and partly shown in dotted lines in Fig. 1. The other rollers in both the ink-founts A are driven in the following manner: A bell-crank O is pivoted on the end of the ink-fount A, as shown in Fig. 7. One arm of this bell-crank O is held against the cam D by the action of the spring E, while its other arm supports one end of the spindle of the ink-transferring roller F, the other end of the spindle being supported by a pivoted forked arm G, as shown in Fig. 8. A ratchet-pawl II is pivoted on the bell-crank O, as shown in Fig. 7, and is held in gear with the ratchet-wheel I by the spring E. As the ink-transferring roller B revolves, the cam D will cause the bell-crank O to rock upon its pivot, so as to first bring the roller F against the main ink-.

ink contained within the fount A.

WVith the view of distributingthe ink evenly over the surface of the roller B, I provide the two rollers K and L, which rest upon the roller B and derive a longitudinal reciproeating motion from its spindle in the following manner: On reference to Fig. 10 it will be noticed that a worm h is formed or secured on the end of the spindle of the roller B. This worm engages with the worm-pinion N, journaled within a bracket O, fixed to the fount A. On each outer surface of the worm-pinion N, I place a cam P, (see Fig. 9, in which only one cam can be seen, the other cam being placed on the opposite side of the bracket,) so as to actuate the pivoted levers Q and R, the cam P, which is seen in Fig, 9, being designed to actuate the pivoted lever R. The throws of the said cams are set at right angles to each other, so that when the lever Q is being thrown in one direction the lever R is moving in the opposite direction.

It is of course understood that the ink roller J revolves in The springs T, as shown in Fig. 8, are provided for the purpose of holding the said 1evers Q and R against their respective cams. The top ends of the levers Q and R are dosigued to fit into grooved disks U, attached, respectively, to the rollers K and L, sequently the said rollers derive a longitudinal reciprocating motion from the movements of the levers Q and R, thereby effectually spreading the ink over the roller B. p

In Figs. 13 and 15 X is a conveyer or carrier, which derives reciprocating motion, as usual, from the rock-shaft it through a rod or arm X which is secured to said shaft and pivotally connected to the front end of said conveyer or carrier. This rod or arm is con nected at its lower end toa short arm 7r, which is operated upon by the eccentric m and the spring Z. When the motion of the rock-shaft has moved the carrier forward, the carrier-fingers a will move the blank forward under the platen-plate U, where it will be heldin position by the stop-fingers D until printed by the type on bed Q, which is brought up to it by the motion of the rack 65 and pinion S at the proper time. The stop-fingers M are then brought down, lugs m, formed at the ends thereof, passing through holes formed in the guards L between which and the conveyer or carriage X the blank passes and holds the sides of the blank against the carrier or conveyer until the type-bed has been lowered after having printed the blank. On the re- IOO Cont ITO carrier-fingers a and b is again reversed, carrier a bringing forward a fresh -gummed blank from the picker A'to be printed under.

the platen-plate U, while the printed blank, being released from the stop-fingers M, is carried forward to the folder, as before men-.'-

tioned. This folder 0 is vertically reciprocated in the same manner as the folder in the above-m entioned patentviz., by the connect-- the spring 0 assisted by the weight of these parts, draws them downwardly, as shown in Fig. 15.

WVhat I claim as my invention is 1. In an envelope-machine adapted to print or emboss blanks during their process of manufacture into envelopes, the combination of the picker A and the folder 0 with the printer B, arranged between said picker and folder, the reciprocating carrier-X, provided with the fingers a and b, the stop-fingers D and M, the rock-shaft H, the'rod I, the spring K, the shaft G, having the cam J, the rod F, the main shaft E, and the intermediate connections for operatin g the printer to printa blank while it is passing from the picker to the folder, said parts being relatively timed and operated, substantially as described, so that the picker will act on the top blank of the pile of blanks while the printer is acting on the blank just removed from the picker by the carrier, and while the folder is at the same time acting on the blank just delivered from the printer, the whole being arranged and operated substantially as described.
